Abstract
The invention relates to a rubber coating composition for steel wire carcass cords of an all-steel radial tire. The composition comprises the following raw material components in parts by weight: 70-90 parts of cis-1, 4-polyisoprene, 20-60 parts of epoxidized natural rubber ENR, 0.5-3 parts of terpene resin, 10-20 parts of silicon-aluminum carbon black, 5-10 parts of carbon black, 10-30 parts of white carbon black, 1-3 parts of cobalt salt and 0.8-1.2 parts of accelerator NS. According to the invention, the white carbon black, the epoxidized natural rubber ENR, the white carbon black and the cobalt salt are matched, so that the adhesive property of the cord thread and the rubber is improved while the performance of the rubber material is satisfied. The terpene resin can improve the adhesive force and improve the mechanical property and the aging resistance of the rubber bonding layer.
Description
Technical Field
The invention relates to a rubber coating composition for steel wire carcass cords of an all-steel radial tire.
Background
The formula of the rubber coating for the tire body cord is always a key factor influencing the performance of the all-steel radial tire, and generally needs to meet the characteristics of high strength, high adhesiveness, low heat generation and the like. With the increasing demands of the automotive industry for high speed, long distance, overload, etc., the functional demand for cord coating formulations has increased further.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a rubber coating composition for steel wire carcass cords of all-steel radial tires.
The rubber coating composition for the steel wire carcass cord of the all-steel radial tire comprises the following raw material components in parts by weight: 70-90 parts of cis-1, 4-polyisoprene, 20-60 parts of epoxidized natural rubber ENR, 0.5-3 parts of terpene resin, 10-20 parts of silicon-aluminum carbon black, 5-10 parts of carbon black, 10-30 parts of white carbon black, 1-3 parts of cobalt salt and 0.8-1.2 parts of accelerator NS.
Further, the cobalt salt includes: 0.1-0.5 part of cobalt boroacylate and 1-2.5 parts of cobalt naphthenate.
Has the advantages that:
according to the invention, the white carbon black, the epoxidized natural rubber ENR, the white carbon black and the cobalt salt are matched, so that the adhesive property of the cord thread and the rubber is improved while the performance of the rubber material is satisfied. The terpene resin can improve the adhesive force and improve the mechanical property and the aging resistance of the rubber bonding layer.
Detailed Description
Example 1
The rubber coating composition for the steel wire carcass cord of the all-steel radial tire comprises the following raw material components in parts by weight: 90 parts of cis-1, 4-polyisoprene, 20 parts of epoxidized natural rubber ENR, 0.5 part of terpene resin, 10 parts of silicon-aluminum carbon black, 5 parts of carbon black, 10 parts of white carbon black, 0.1 part of cobalt boracylate, 1.4 parts of cobalt naphthenate and 0.8 part of accelerator NS.
Example 2
The rubber coating composition for the steel wire carcass cord of the all-steel radial tire comprises the following raw material components in parts by weight: 70 parts of cis-1, 4-polyisoprene, 60 parts of epoxidized natural rubber ENR, 3 parts of terpene resin, 20 parts of silicon-aluminum carbon black, 10 parts of carbon black, 30 parts of white carbon black, 0.5 part of cobalt boracylate, 2.5 parts of cobalt naphthenate and 0.8-1.2 parts of accelerator NS.
According to the invention, the white carbon black, the epoxidized natural rubber ENR, the white carbon black and the cobalt salt are matched, so that the adhesive property of the cord thread and the rubber is improved while the performance of the rubber material is satisfied. The terpene resin can improve the adhesive force and improve the mechanical property and the aging resistance of the rubber bonding layer.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The above-described embodiments of the invention are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, and not by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
